Report #89971

[tooling] Agent wastes tokens calling list\_directory tool repeatedly to explore file structure

Expose directories as MCP Resources with URI templates \(e.g., file:///\{path\}\) and set mimeType to inode/directory. The agent can then discover children via resources/list without function calls.

Journey Context:
Tools require execution to see what's available; resources expose static metadata. For browsing patterns \(filesystems, APIs, registries\), URI templates let the LLM see the hierarchy in the context window without token-costly trial-and-error. This shifts discovery from runtime execution to static context.
